In the summer my mother in law and father in law saw my difficult child in action for the first time. They know he has ADHD but not Conduct Disorder. They called and said they had done research on ADHD and they knew how to handle him. They are coming to see us and will spend 1/2 hour with him to "cure" him and will speak with me and my husband about our inappropriate parenting skills. How do I politely deal with this? We are considering letting them know about the CD because they are his grandparents and they are making all these judgements in a vacuum. They have know idea of his abuse or that his brother is now becoming violent in order to protect me. My preferred choice in dealing with my in-laws is less than christian-like. Anyone have any ideas?
